次声监测技术是《全面禁止核试验条约》规定的四种监测技术手段之一,用来监测大气层中的核爆炸。根据次声台站监测过程中经常需要分析处理的次声信号类别,着重介绍分析爆炸、火山喷发、地震等令人震撼的事件以及微气压、海浪等日常司空见惯的自然现象激发次声波的机理及其信号特征。这些特征对于次声监测数据处理、去噪降噪、目标分类与识别等具有重要意义。
Infrasound monitoring technology is one of the four monitoring techniques stipulated in the Comprehensive Test Ban Treaty and is used to monitor nuclear explosions in the atmosphere. According to the types of infrasound signals often analyzed and processed during infrasound station monitoring, this paper focuses on the analysis of shocking events such as explosions, volcanic eruptions and earthquakes, as well as the mechanism of stimulating infrasound by natural phenomena such as micro-atmospheric pressure and ocean waves Signal characteristics. These features for infrasound monitoring data processing, denoising noise reduction, target classification and identification is of great significance.
